Abstract

本实用新型涉及一种变频电缆，由内到外包括线芯、包带层、隔离层、导体接地层、护套，线芯由内到外包括导体、绝缘层、屏蔽层，导体接地层由多根细铜丝紧密排列组成，细铜丝缠绕在隔离层外。本实用新型抗电磁屏蔽性能好，感应电抗值小。

Description

变频电缆
技术领域
本实用新型涉及一种电缆，尤其是一种变频电缆。
背景技术
变频电缆主要用于变频电源和变频电机之间连接用的电缆，现在使用的变频电缆抗电磁屏蔽性能不好，感应电抗值较大，不能很好的在变频电路中作为动力传输线。
发明内容
本实用新型的目的在于克服现有技术的缺陷，提供一种抗电磁屏蔽性能好，感应电抗值小的变频电缆。
为实现上述目的，本实用新型采用一种变频电缆由内到外包括线芯、包带层、隔离层、导体接地层、护套，线芯由内到外包括导体、绝缘层、屏蔽层，导体接地层由多根细铜丝紧密排列组成，细铜丝缠绕在隔离层外。
本实用新型进一步设置为所述线芯有3根，按中心对称排列设置在包带层内。
本实用新型的有益效果是导体接地层不仅充当接地线，感应电抗小，而且还能作为屏蔽层，能与线芯上的屏蔽层构成双重屏蔽结构，使本实用新型具有抗电磁干扰、抗雷击和高次谐波的影响；3根线芯按中心对称分布使三相供电更加平衡，相线抗阻均匀而且较低，改善了供电品质。
附图说明
图1是本实用新型实施例截面结构示意图。
具体实施方式
如图1所示，本实用新型的具体实施例是一种变频电缆，变频电缆包括线芯、包带层4、隔离层5、导体接地层6、护套7，线芯由内到外包括导体1、绝缘层2、屏蔽层3，线芯有三根，三根线芯按中心对称排列设置，包带层4包裹在三根线芯外，隔离层5、导体接地层6、护套7依次设置在包带层4外，导体接地层6由多根细铜丝紧密排列组成，细铜丝缠绕在隔离层5外，护套7包裹在导体接地层6外。
